Application filed July 19, 1927, Serial No.

- that type of such machines in which the art-iclc together with the wrapper-is conveyed from a lower supply position into an upper folding position.

effecting the In the known machines of this type the paper wrapping is introduced into the machine in such a. way, for instance cut off from a reel of paper located with its axis parallel to the main shaft of the machine, that it is situated in a position at right angles to the folding mechanism above the article to be wrapped. In this design of the machine a comparatively complicated driving mechanism is required for the folding device wrapping.

The object ofmy invention is to simplify the wrapping process and in particular theentire operating gear for the folding device. effecting the wrapping.

' An essential new feature of my invention is the provision of a device which when the article is elevated engages the wrapper carried along by the article or the wrapper and the article and performs such an angular movement that the wrapper is brought from the original position at right angles to the folding mechanism into a diagonal po-. sition to said mechanism, whereby the now following folding of the wrapper against the bottom of the article by the folding device is greatly simpli fied.

Further novel features of my invention will appear as the description proceeds.

An embodiment of my invention is illustrated in the drawings aflixed hereto, the example shown being a machine for wrapping roundloavcs of bread. 'In the drawings is:

of reference throughout all the figures of the drawings.

Referring to the drawings, it will beobserved that the framework of the machine consists substantially of-upright side frames 400, 401 connected with each other by suitable transverse rods.

.In suitable bearings of the said side frames is journaled the main driv'ing'shaft 41 which is continuously rotated from a suitable prime mover by means of a pulley 42. The rotation of the shaft 41 is transmitted to a shaft 37' likewise journaled in bearings of the side frames, by means of spur wheels 38, 39 and 40. Upon this shaft 37 are mounted suitable eccentrics for operating various constituent parts of the machine hereinafter described.

The introduction of the loaves B to be wrapped into the machine takes place by a plurality of conveyer belts l which in a similar manner as the belts 120 described hereinafter and illustrated in Fig. 2, run over pulleys or rollers a series of which is shown at 404 in Fig. 1. The drive of the rollers 404 is effected by means of a toothed wheel 406 rotatable upon the shaft 405 of these 00 rollers by the aid of a toothed quadrant 407 pivoted upon a stud 408 upon the side frame 400 and operated by means of its extended arm 409 by a joint- 410 from the arm 411 of a. bell-crank lever. This lever is mounted upon a shaft 413 fixed in the side frames and is kept in engagement with a. suitable eccentric of the shaft 37 by an anti-friction bowl 414 mounted upon the other arm 411 and controlled by a spring not shown in the 90 drawings. The spur wheel 406 does not operate the shaft 405 directly, but through the agency of a suitable well-known free wheel mechanism in such a manner that the shaft 405 is rotated'during of the quadrant 407 only.

At the leading end of the conveyor belt 1, the bread reaches the position I of an elevating plunger 2 adapted to reciprocate vertically in sucha manner that the bread is conveyed from the lower position I into the upper wrapping position II. This elevating plunger is mounted upon a sleeve or bushing 54 which is journaled upon the stud 55' of a rod or rail 55 which is guided in a sliding track 57 fixed, to the machine frame,

the downward stroke effected during the i which is pivoted to a connectin by means of a ball-bearing 56, so that the plate 2 is able to rotate freely. For the purpose of reciprocating the rod 55 vertica'lly an eye 58 of the said rod is engaged by means of a joint 59 by one arm of a double-armed lever capable of rocking upon the shaft 413. The other arm 61 of the said lever is engaged by a rod not illustrated in the drawing, which is driven in well-known manner from an eccentric upon the shaft 37. The lower feed of the loaf B is limited by a stop 62 which is adjustably mounted on a pedestal-like extension 63 of the guide 57.

Above the bread B located in the position I, there is provided a plate 15 with an opening 16 for the bread B which is mounted upon pillars 100 and upon which is placed the wrapper'U for enveloping the bread.

The wrapper U may be withdrawn from a pile and be pulled or pushed upon the said plate 15 by grippers or the like means. In

the case illustrated, the wrapper U is cut ofi? from a web of paper P which is pulled off a paper reel R, see Figs. 3 and 4. The core 22 of said reel is journaled in arms 25 of pedestals 26 mounted upon the machine framing. For unwinding the web from the said reel, I employ a feed roller 18 in conjunction with feed, rollers 19 which are mounted upon a-shaft 20. The feed roller 18 is intermittently driven, while the rollers 19 are loosely rotatable journaled by means of the shaft 20. 18 is effected by means of a toothed quadrant 21 journaled upon the stud 23 which is fixed upon the pedestal 24. The quadrant acts by means of aspur wheel 28 mounted upon the shaft 27 of the roller 18 upon a suitable freewheel mechanism of well-known design in such a manner that a rotation of the feed roller 18 in the direction of the arrow is upward oscillation of the quadrant 21 only, and on the other hand no rotation of the roller 18 takes place during the downward swing of the quadrant ,21. The drive of the quadrant 21 takes place by a connecting rod 31 engaging the quadrant at 30 from the crank pin 32 of a crank disc 33, which is keyed to the shaft 34 journaled in the standards 26. The shaft 34 is continuously rotated by the bevel wheels 35, 36, see in particular Fig. 3 of the drawings, of which the latter is keyed to the shaft 37 mentioned above.

The shaft 20 of the feed rollers 19 is journaled in arms 43 which in their turn are journaled upon a rod- 44 journaled. in eyes 45 of the standards 24. The right-hand side arm 43 in Fig. 3 of the drawing is provided with an extension 46 which is at 47 engaged by a connecting rod 48 the other. end of rod 49. The latter is pivoted to the stan ard 26 at .50 and is kept by a bowl 51 in engagement with The drive of the feed roller descends,

a suitable cam disc indicated at 52 upon the shaft 34 under the control of a spring not shown in the drawings in such a manner that the feed rollers 19 are raised by means of the arms 43 around the shaft 44 by the cam of the cam disc off the feed roller 18 and are pressed against the feed roller 18 by the spring when the anti-friction bowl is at the narrowest place of the cam disc. The control arrangement is such that the feed rollers 19 are pressed down when the feed drum 18 is turned in the direction of the arrow and that the feed rollers 19 are raised ofi the drum 18 when the latter is stationary. -The feed device described is so set that during each rotation of the feed drum 18 the paper web P is fed forward by the drum in cooperation with feed rollers 19 by a piece corresponding with the desired length of the wrapper upon the plate 15 whereupon the wrappenU is cut off the paper web P when the feed drum 18 has come to rest, by means of a suitable cutting device.

The cutting device operating in the manner of shears consists of a stationary upper knife 149 and a vertically reciprocatable and simultaneously in its bearings rotatable lower knife 150 which is bolted to the transverse beam 151 and is rotatable in the arms 153 knife 150 against the stationary upper knife 149. The arms 153 and 153' are keyed to the shaft 170. The arm 153 is extended towards the other side by the arm 155 and this latter arm is by a connecting rod 156 connected with the driving lever 157 by pins and is o erated by an eccentric 158 fixed upon t e shaft 34 and roller 159.

On referring to Figs. 1 and 4 of the draw: ings, it will be noticed that the loaf of bread introduced into the machine upon the lower fee'd track 1 encounters a fiap 160 which by the shaft 162 is journaled in the pedestals or standards 163 and 164 secured to the plate 15. When the loaf B forces the flap 160 upwards, as in Fig. 1, the lever 167 rotatable in the standard 166 is turned towards the left and the upper arm 165 towards the right by the lever 161 mounted upon the shaft 162 by means of the draw bar 168. This releases the nose 43' feed rollers 19 are able to come in contact with the lower feed drum at the proper moment and the paper required for the loaf; B is pushed forward and cut off the web. If on the other hand, no loaf arrives, the flap 160 the lever 165 moves towards the left and prevents by the locking operation of the nose 43, the upper rollers 19 from being forced against the lower feed roller 18. No paper is unwound from the reel in this case.

of the arm 43, so that the upper V 83 ofthe eye suitable rod not shown,

Above the station I, there is provided a device by means of which the paper wrapper out off in the position a, Fig. 2, is turned into the diagonal position (a) indicated in broken lines in Fig. 2. This device consists in the case illustrated of a counter holder 64 which is adapted'to carry out an up and down motion as well as a positive partial rotary motion. For this purpose, the holder 64 is mounted, for instance, upon a rod 65 consisting of a steel tube which .is guided vertically in stationary. bushings 66 and 67. The bushing 67 is" attached to a head piece 68 fixed upon a rod 69 which in its turn is fixed in an eye 70. This eye carries the said bushing 66 and is mounted on a standard 71 which is fixed to a slide track 117, see also Fig. 4. The slide track 117 is mounted on a bifurcated pedestal 7 2 which is attached to the side frames 400, 401 in the manner illustrated in Fig. 4.

The up'and down motion of the rod 65 and thus of the back holder 64' is effected by means of the levers 7 3 and 74 fixed upon a stud 77 journaled in a bearing 75 of the standard or pedestal 71 and which engage studs 80 and 81 of an eye 83 by means of hinged rods 78, 79. The vertical rocking motion of the arms 73, 74 is effected by means of a rod 84 which engages an extended arm 74 of the arm 74 and is pivoted to one arm of a bell-crank lever 851.' This bellcrank lever is adapted to rock upon the shaft 413, and its other arm 85' is engaged by a which is driven by an eccentric upon the shaft 37. v

The .rod 65 is freely rotatable journaled in the said eye 83. For this purpose the eye 83 is rotatably. mounted upon the tube 65 between two collars 86, 86" 1y fixed upon the tube 65. To secure the eye 83 against lateral displacement an arm embraces the guide rod 69 by means of a semi-circular fork 83".

For the purpose of bringing about the positivepartial rotation of the rod or tube 65 together with the counter or back holder 7 64 during its up and down motion, a helical groove 84 is provided in the rod which lsengaged by a pin 85 fixed upon the eye 66, the groove 84 being so designed that the tube 65 with the holder 64 performs an angular motion of about 45 during the up and down 1motion. f

eow tie upper wrap in osition o the bread indicated by p b is provided a device by which when the bread is raised from the'position I into the said position II, the wrapper U is folded around the bread from the top downwards. This is effected in the machine illustrated by a ring-shaped brush which preferably has a smaller diameter than the diameter of the loaf B. x

The said annular brush is mounted upon the drawin gs,

which are rigid-- II in Fig. 1,'there contact with wrapper a ring 89 provided with a 89 and attached on the one hand to the standard 117 and on the other hand to the upper conveyor track 121 by means of lateral flaps 89". In the design illustrated in the annular brush consists of a plurality of individual brushes suitably spaced upon the ring 89. Preferably the brushes taper from the top downwards which result may be obtained in a simple manner by providing below the ring 89 brushes 88, which are shorter and do not project so far into the opening 89' as the passage opening brushes 88 mounted upon the ring 89, see- Figs. 1 and 5. In this way, the wrapping is smoothly folded around the article, such as a loaf of bread, when it ascends which action may be assisted by guide plates 500 of sheet iron attached to the ring 89 between the sections of the brush and extending downwards and-backwards and which guide thc corners of the wrapping, sheet U into the lower annular brush 88 when the bread ascends.

The machine described hitherto functions in the following manner:

When the elevatingplunger 2, after it has raised a loaf, has been again returned into the lower position shown in Fig.1 by its operating mechanism described, the conveyor belts 1 are by nism advanced by such a distance that the next loaf of bread B is conveyed upon the plate 2 of the elevating plunger. Simultaneously the front end of the paper web P has their operating mecha-.

has cut off a wrapper U from'the paper 1 web P which now occupies the position indicated by the letter a in Fig. 2 upon the plate 15. Meanwhile the counter-holder 64 has by means of its operating mechanism described been lowered from its upper inoperative position, not shown, into its lower operative position shown in Fig. 1, above the cut off wrapper U, the counter holder having simultaneously performed a rotation of 45 due to the described cooperation of the helical groove 84 with the pin 85. Now the bread B is raised by the plunger from the position I into the bread B carries the wrapper U along and encounters the lower annularly recessed face of the back holder 64. As soon as this has occurred, the back holder 64 is also moved upwards by its operating mechanism described so however that it remains in good and bread. Since duning the elevating motion of the back holder 64 due to the cooperation ofhelical nut 84 and pin 85 the back holder 64 is turned back through an angle of 45 and the plate 2 of the elevating plunger is easily rotatable upon the rod 55, the angular roflaps of the wrapping, so

tation of the back holder 64 also effects a rotation of the bread and the wrapper by into the diagonal position indicated by (a) in Fig. 2. During its ascent, the bread B passes together with the wrapping U first into the wider lower annular brush 88' and then into the narrower upper annular brush 88,

whereby the wrapping is folded around the bread in the manner shown in position II, the guide plates 500 smoothing down the that it is now only necessary to fold the lower edge U of the wrapping, which owing to the diagonal position of the wrapper may be carried out far more easily by the simple folding members hereafter described, than if the wrapper had maintained its original square position.

The folding over of the side flaps is effected by oscillating folding slides 101 and 101 which are mounted on levers 102, 102' which in their turn are journaled upon bolts The bolts are fixed upon the standard 117. Cranked arms v 107, 107 of the levers 102 102' are engaged by rods 109, 109 by means of universal joints 108, and these rods are coupled with levers 111, 111' by .means of universal joints 110. The latter levers are adapted to rotate upon the shaft 413 and are kept in engagement with suitable eccentrics of the shaft 37 by means of antifriction bowls and springs. The eccentrics control and drive the levers 111 and 111 in such a way that after the bread has been elevated, the folders 101, 101 are moved from their outer inoperative position into the inner folding position shown in Fig.

' 2. As soon as the folding slides 101, 101' support' the bread sufficiently, the lifting plunger 2 ,returns from its upper into its lower position.

In order to hold the bread securely in the wrapping position II, lateral pressing or gripping members are preferably provided which grip and hold the bread at its sides when it has reached the upper position II. In the design illustrated by way of example, they consist of jaws 501 preferably constructed of resilient material which are mounted on arms 503 by angle irons 502.

These arms are freely rotatable journaled upon the studs 103, 103 of the folding levers 102, 102 and are connected by a spring 504 extending between downwardly directed angular projections 505 of the said arms together.- In the event that no loaf has reached the wrapping position this inwards motion of the jaws 501 is limited by set screws 506 which are adjustably screwed into the said angular extensions 505 and which come incontact with the sides of the standard 117 when the jaws 501 move too far inwards. Beyond the fulerums 103 and 103, the arms 503 are furnished with segment-shaped extensions 508 provided with motion under the action of the spring 504 until they come in contact with the bread. During the further inwardsvmotion of the folding slides 101, 101', the arms 107, 107 then move away from the pins 510.

For folding over the rear flap of the Wrapper projecting downwards, a folding slide 115 is provided which is mounted upon a rail 110 which is adapted to slide horizontally in the standard 117. The rail 116 is engaged by a lever 432 by means of a standard 430 and joint 431. The lever 432 is journaled upon the shaft 413 and is kept in contact with an eccentric upon the shaft 37 by means of an anti-friction bowl 433 and a spring not shown in the drawing. During the return motion of the folding slides 101, 101 into their inoperative enter position, thefolding slide 115 is moved forward by its operating mechanism described, whereby it folds the depending back flap of the wrapper U against the bottom and simultaneously supports the bread. The folding slide 115 remains in this position, until the bread B has been advanced from the position II into the pgsition III on the upper conveyor track 1 1. I

At the station II, there is also provided an arresting device for the purpose of retaining the bread during the folding process described in the position II, This device consists of a flap door 450 rotatable at 451 in a hinge 452 and maintained in the position shown inFig. 1 by a spring not shown, but adapted to be swung towards the right by 'the advancing bread. The said hinge 452 is adj ustably mounted upon an angle 453 which in its turn is adjustably fixed at the eye 66.

The folding over of the front flap still projecting downwards of the wrapping U takes place during the advance of the bread by means of a slide 118. This slide is by means of an angular piece 119 mounted upon a rail 120 which is adapted to slide longi-' t-udinally in the standard 117. This rail is by means of an eye 434 fixed upon it and a joint 435 engaged by a lever 436 adapted to rock upon the shaft 413 and kept in engagement with a cam upon the shaft 37 by means of an anti-friction bowl 437 and a spring not shown in thedrawing. When the slide 118 is pushed by its operating mechanism described towards the right, it. moves the bread During the standards 438, 438

B into the position III, whereby the front flap of the wrapper is folded against the bottom of the bread by means of the front edge of the upper discharge track 121. Preferably. a freely rotatable roller 502 journaled in eyes 501 mounted on the conveyor track 121 is provided in front of the inlet edge of the said conveyor track which effects a smooth folding over of the lower flap of the wrapping.

Below the position III, there may be provided electric heating members 128 of any suitable design in the event of paper impregnated with Wax or paraffin being used as wrapping for the article. WVhen the wrapped up loaf or the like has reached the position III, the-wax or paraflin is then melted by the. electric heaters 128. During the further progress, the impregnating medium becomessolid again and thus efiectively seals the package. At both sides of the upper discharge track 121, there .are provided rails 123 which serve for the lateral guidance of the bread. The further advance of the loaves upon the track 121 takes place by the loaves following. i

From the track 121 the wrapped up articles pass on to the conveyor belts 130 guided upon rotatable rollers, the series of rollers ad Ommg the track 121 being indicated by the reference numeral 131. i The rollers rotate loosely upon the shaft 439 fixed-in the standards 438, 438. The standards 438, 438" are mounted upon the side frames 400 and 401 of the machine framing.

In order to force the bread at station IV with ing elements 128 against the upper conveyor track 121 and thus to obtain a satisfactory seal, a special pressing device may also be provided at this station. This device consists in the embodiment illustrated of a plate 444 fixed upon a bolt-440 journaled in the mounted upon the standards 441, 441. Upon theplate 444 is fixed an arm 442 pulled downwards by a spring 443, so that the plate or flap door 44 also exerts a yielding pressure upon the top of the bread at station IV. I
